Abstract
Abstract A vessel for use in removing a floating contaminant liquid such as oil from the surface of water has a hull forming an immersed inverted channel into which surface layers flow as the vessel advances, the hull being shaped so as to guide the liquid into accumulation zones from which the liquid is drawn by a pump into settling tanks disposed in pontoons on each side of the hull, the water being discharged from the tanks and the contaminant liquid being collected in the tanks.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
139 words
A VESSEL FOR COLLECTING A LIQUID FLOATING ON THE SURFACE OF A BODY OF WATER, SAID VESSEL COMPRISING A V-SHAPED HULL PORTION, A DECK THEREOVER, AND CATAMARAN HULL PORTIONS CONNECTED TO SAID DECK AT EACH SIDE OF SAID HULL PORTION, A DOWNWARDLY OPEN COLLECTING CHANNEL STRUCTURE LOCATED BENEATH SAID DECK BETWEEN SAID HULL PORTION AND SAID CATAMARAN HULL PORTIONS AT EACH SIDE OF SAID V-SHAPED HULL PORTION, THE SURFACE OF EACH SIDE OF SAID HULL, ARRANGED IN AN UPWARDLY INCLINED V, JOINING AT ITS UPPER EDGE THE DOWNWARDLY OPEN SIDE OF SAID COLLECTING CHANNELS WHEREBY LIQUID DISPLACED BY SAI V-SHAPED HULL PORTION IS DEFLECTED INTO SAID DOWNWARDLY OPEN COLLECTING CHAMNELS, DIVIDER MEANS LONGITUDINALLY SPACED WITHIN SAID COLLECTING CHANNELS DIVIDING SAID CHANNELS INTO A PLURALITY OF SEPARATED FLUID COMPARTMENTS, AND MEANS FOR REMOVING COLLECTED FLUID FROM EACH OF SAID COMPARTMENTS.

Claim 3
Dependent Claim
45 words
A veSsel as set forth in claim 1 wherein said V-shaped hull portion is provided with a plurality of spaced apart ribs extending angularly and rearwardly toward the stern of the vessel to direct said fluid to be collected toward said downwardly open collecting channels.
Claim 4
Dependent Claim
34 words
A vessel as set forth in claim 1 wherein said divider means are comprised of spaced apart transverse fins extending over the entire width and the entire height of said downwarly open collecting channels.
Claim 5
Dependent Claim
24 words
A vessel as set forth in claim 3 wherein said transverse fins are upwardly inclined from the bow to the stern of the vessel.
Claim 6
Dependent Claim
36 words
A vessel as set forth in claim 3 further comprising a plurality of auxiliary transverse fins in each compartment extending across the width of said downwardly open collecting channels but spaced from the uppermost wall thereof.
Claim 7
Dependent Claim
40 words
A vessel as set forth in claim 3 wherein each of said downwardly open collecting channels is provided with longitudinal fins extending throughout the entire length of said channels perpendicular to but spaced from the uppermost wall of said channels.
Claim 8
Dependent Claim
40 words
A vessel as set forth in claim 1 including at least one aperture extending through the upper portion of each of said fluid compartments and means for drawing through said apertures the liquid accumulated in each of said fluid compartments.
Claim 9
Dependent Claim
32 words
A vessel as set forth in claim 7 including at least one air exhaust conduit communicating with each of said fluid compartments at a location close to said aperture in said compartment.
Claim 10
Dependent Claim
27 words
A vessel as set forth in claim 7 further comprising storage tanks located in said catamaran hull portions for the collection and decantation of the collected liquid.
Claim 11
Dependent Claim
93 words
A vessel as set forth in claim 9 wherein said means for drawing the collected liquid through the apertures comprises manifold means disposed in communication with the apertures of each compartment, conduit means connecting said manifold means with one of said tanks, passage means interconnecting said tanks and a suction pump arranged to withdraw the lower layers of liquid contained in said tanks and discharging the same into the surrounding water to create a suction in the tanks suitable for the purpose of drawing into the latter the liquid collected in said compartments.
Claim 12
Dependent Claim
63 words
A vessel as set forth in claim 10 including auxiliary settling tank means disposed adjacent said decantation tanks, flow passage means connecting said decantation tanks with the lower part of said auxiliary settling tank means and a decantation pump adapted to take off the top layers of liquid contained in said decantation tanks and conveys the same to said auxiliary settling tank means.
